The nearest mapped lake is Unnamed lake (mapped on OpenStreetMap), 180 m from the project’s RERA map point.

The site boundary is not published as a shape, so its nearest edge can be closer than this point. Whether any building sits inside a lake buffer can only be checked on the approved plan.

The buffer rule

Bengaluru’s lake buffer rule has changed over time: the National Green Tribunal ordered a 75 m buffer in May 2016; the Supreme Court set that order aside on 5 March 2019, leaving the 30 m buffer of the Revised Master Plan 2015. Check the current rule and the approved plan before relying on either number.

Not every approval applies to every project (for example, smaller projects may not need an environment clearance). Each phase is registered separately; this list is for the phase named above.
